A 401(k) is a retirement savings plan offered through your employer. Money you contribute to your 401(k) grows tax-deferred, meaning you don't pay income taxes on the earnings until you withdraw the money. However, the government has specific rules about when you can withdraw these funds without penalties.

The most important age threshold is 59½. If you withdraw money from your 401(k) before age 59½, you typically owe a 10% early withdrawal penalty on top of regular income taxes. For example, if you withdraw $10,000 at age 45, you would owe $1,000 in penalties plus income taxes on the full $10,000 amount. This penalty exists to discourage people from raiding retirement savings early.
At age 59½, you can withdraw your 401(k) money without the 10% penalty, though you still owe income taxes. This is why 59½ is often called the "magic number" for retirement planning. If you retire at 62 and wait until 59½ to access your 401(k), the penalty no longer applies.
There are some exceptions to the early withdrawal penalty. Certain circumstances may allow penalty-free withdrawals before 59½, including:
It's important to understand that even with these exceptions, you still owe income taxes on withdrawn amounts. The penalty is just waived. According to the IRS, approximately 20-25% of 401(k) holders take early withdrawals, often due to financial hardship or job changes.
Takeaway: Know your current age and understand that withdrawals before 59½ typically cost 10% in penalties plus taxes. If you're within five years of 59½, waiting may save substantial money in penalties alone.
Once you reach age 73 (as of 2023, changed from 72 under the SECURE Act 2.0), the IRS requires you to withdraw a minimum amount from your 401(k) each year. These are called Required Minimum Distributions or RMDs. This requirement exists because the government wants to eventually collect taxes on all the money you've been deferring.

The RMD amount is calculated by dividing your 401(k) balance on December 31 of the previous year by a life expectancy factor published by the IRS. For example, if you have a $500,000 balance and your life expectancy factor is 25.5, your RMD would be approximately $19,608 for that year. You must withdraw at least this amount to comply with tax law.
The penalties for not taking your RMD are severe. If you fail to withdraw the required amount, you owe a 25% excise tax on the shortfall. If your RMD is $20,000 and you only withdraw $15,000, you owe a 25% penalty on the $5,000 you missed—that's $1,250 in penalties. The IRS recently reduced this from 50%, but it's still a significant consequence.
There are some exceptions and strategies related to RMDs:
According to a survey by Fidelity, approximately 10% of 401(k) holders miss their RMD deadlines in any given year. Setting a calendar reminder in November is a practical way to avoid penalties.
Takeaway: Track when you turn 73 and understand your RMD amount. Set a yearly reminder to take your distribution by December 31. Calculate your specific RMD using IRS tables or consult your plan administrator.
When you leave a job, you have several options for your 401(k). Understanding these options can help you avoid unintended tax consequences. The decisions you make when changing jobs significantly impact your long-term retirement savings.

If your former employer's 401(k) balance is under $5,000, some plans may force you to take a distribution. The employer must notify you in writing before doing this. If they do distribute your balance without your permission, you have 60 days to roll it into an IRA or another 401(k) to avoid taxes and penalties. This is called a rollover.
With larger balances, you typically have four options:
If you roll money between plans, use a direct rollover when possible. With a direct rollover, the money goes directly from one institution to another, and 20% is not withheld. If the money is paid to you first, your plan administrator typically withholds 20% for taxes, and you have only 60 days to deposit the full amount (including the withheld 20%) into another retirement account. If you don't, the withheld amount is treated as a taxable distribution.
When an employer terminates a 401(k) plan entirely, they must distribute all remaining balances within a certain timeframe, typically between 30 days and a year depending on the termination type. You'll receive notification about your options and deadlines.
Takeaway: When changing jobs, contact your old plan administrator and ask about rollover options. A direct rollover to an IRA or new employer plan preserves your tax deferral and typically avoids the 20% withholding.
Some 401(k) plans allow hardship withdrawals, which permit taking money out before 59½ without the 10% penalty. However, not all plans offer this feature, and the rules are restrictive. You must still pay income taxes on the withdrawn amount, even though you avoid the penalty.
